Non-Uniform Quantization
Full Form of NUQ
What is NUQ?
Non-Uniform Quantization (NUQ) is a signal processing technique where the quantization step size varies across the input range, unlike uniform quantization which uses fixed steps. This approach allocates more levels to regions with higher signal probability or perceptual importance, reducing overall distortion for a given number of bits. NUQ is widely used in audio compression (e.g., μ-law and A-law companding) and image processing to improve fidelity at low bitrates. In India, NUQ is taught in graduate-level digital communication and multimedia courses, especially in institutions like IITs and NITs. It is applied in telecommunication systems, VoIP codecs, and streaming services popular in the Indian market. Understanding NUQ is crucial for engineers working on bandwidth-efficient transmission in India's expanding digital infrastructure. The method balances computational complexity and quality, making it a key concept for wireless and optical communication exams such as GATE and IES. Its role in reducing data size while maintaining intelligibility underpins many modern communication protocols used across the country.
